That is, as shown in FIG. 2, the key device 50 is in an OFF mode in which all power and signals of the train are cut off when the direction of the master key 60 is horizontal (①), and one side When it rotates 45° in a clockwise direction (clockwise), it becomes an inspection mode in which power and all other signals are applied except for the propulsion signal of the train (②). The train turns into an ON mode in which it can start (③).

The key used for such train inspection is the Mascon key used by the driver. Therefore, during the inspection process, the inspector may place the Mascon key in the on mode by mistake, and the inspection may be performed. In this case, a very dangerous situation such as personnel accidents of field workers may occur because the train starts by operating the main handle. That is, the inspector must set the key device to the inspection mode in which the train propulsion signal is not input by rotating the Mascon key exactly 45°, but it is often turned to ON mode by turning it to 90° by mistake. are doing This is because the driver's driving Mascon key is used in combination with the inspector's inspection Mascon key.

Referring to FIG. 3, the inspection key device 100 of this embodiment includes a guide housing 110 that guides the insertion of the inspection key 120, and a guide housing 110 inserted into the guide housing 110 to rotate to set the inspection mode. It is composed of a key 120 for inspection.

The guide housing 110 guides the insertion of the key 120 for inspection, and a key insertion hole 111 into which the key 120 for inspection is inserted is formed in the center of the hexahedron-shaped main body, and the key insertion hole 111 ) The guide protrusion 112 protrudes from the inner wall. The key insertion hole 111 has a circular shape corresponding to the rotational axis 121 of the key 120 for inspection to insert the rotational shaft 121, and the guide protrusion 112 has the rotational shaft 121 in a specific circumferential direction. Guides insertion into The guide protrusion 112 may protrude to a predetermined length. A control structure (not shown) is installed below the guide housing 110 to turn on/off the contact point of power and signal according to the operation of the inspection key 120 and the driving key.

The inspection key 120 is inserted into the key insertion hole 111 of the guide housing 110 to rotate the control structure disposed below the guide housing, and is formed on the rotation shaft 121 and the upper end of the rotation shaft 121. It may be composed of a handle 122 formed.

The rotating shaft 121 has a cylindrical shape having a diameter corresponding to the inner diameter of the key insertion hole 111, and a lower end portion is formed with an engaging structure matching the control structure. In addition, the rotating shaft 121 includes an insertion guide groove 123 formed on the circumferential surface in the longitudinal direction and a rotation guide groove 124 formed along the circumferential direction. That is, the insertion guide groove 123 is formed with a predetermined length vertically upward while the lower end of the rotation shaft 121 is opened, and the rotation guide groove 124 is formed in the circumferential direction from the upper end of the insertion guide groove 123, that is, horizontally. formed by extending in the direction

The insertion guide groove 123 guides the insertion and removal of the inspection key 120, and the rotation guide groove 124 guides the rotation of the inserted inspection key 120. Specifically, at the position where the insertion guide groove 123 of the key 120 for inspection coincides with the guide projection 112 of the guide housing 110 (a position where the power is turned off), the guide projection 112 is inserted into the guide groove Since it can move along 123, the rotating shaft 121 can be inserted or removed in a vertical direction, and after the rotating shaft 121 is completely inserted, the guide protrusion 112 moves along the rotating guide groove 124. Therefore, the rotation shaft 121 can rotate in the horizontal direction.

Therefore, the inspection key 120 can be inserted and removed only at the off position by the insertion guide groove 123, and can be rotated after being fully inserted in the off position by the rotation guide groove 124. there is.

At this time, the control signal (①) includes all signals necessary for driving the vehicle, such as lighting, air conditioning, broadcasting, heating and cooling.

However, as shown in (b) of FIG. 4, the inspection key 120 rotates reciprocally only within a 45° rotation angle. In this way, when the inspection key 120 is rotated at 45 ° and is in the inspection mode, all control signals (①) except for the propulsion signal (②) are input to the train as shown in FIG. It becomes a state where all operations can be inspected.

The inspection mode in the main controller of the train is the minimum device provided in the train to perform safety and is configured to apply to the safety regulations of the railroad car, and the control signal (①) applied in the inspection mode is like this. Includes all signals applied according to

On the other hand, a key device not equipped with an inspection mode may be installed in the main train controller of the old model. In this case, after replacing the key device assembly including all components such as the mask key for inspection and the guide housing, the mask key for inspection of this embodiment can be applied.

As described above, the present invention can prevent dangerous situations that may occur due to an inspector's key manipulation mistake by separately providing an inspection-only Mascon key capable of rotating only to the inspection mode.
